Ok, nothing serious but DS (11) was at a sleepover party followed by a trip to skatepark about 1 hour, 20 mins drive away. Invite said a specific time for pick up. Friend lives in same street so DS would have walked home anyway. However after he still hadn't appeared one hour after said time I started to get a little concerned. I sent a text just asking when boys were likely to be home but got no response. They finally got back 2 hours after they said they'd be home. Still no explanation or reply.
I can understand not replying to text if driving but surely the parents would have known they were going to be late even before they left to drive home and even once home, would they not have texted something about traffic being bad or whatever the delay was.
